DUMPING CAB OR WAGON.

Specification of Letters Patent.

ratented June 5, 1906.

Application filed December 16,1905. Serial No. 292,041.

To all whom it may concern:

Be it known that I, EDWIN S. BOYD, a citizen of the United States of America, residing at Norris City, in the county of White and State of Illinois, have invented new and useful Improvements in Dumping Cars or Wagons, of which the following is a specification.

This invention relates to improvements in the construction of cars or wagons of the dumping type, and has for its object to provide simple and effective means whereby the load may be conveniently dumped while the vehicle is in motion and the parts of the dumping mechanism reset to close the outlets in the body of the vehicle and adapt the same for the reception of a succeeding load.

In the accompanying drawings, Figure 1 is a side elevation of the body of a vehicle constructed in accordance with my invention, showing the dumping-doors closed. Fig. 2 is a central vertical longitudinal section of the same. Fig. 3 is a front elevation of the vehicle. Fig. 4 is a central vertical transverse section looking toward the rear of the vehicle-body. Fig. 5 is a top plan view, a portion of the deflector being broken away to show the cord or cable connected with the rear ends of the doors. Fig. 6 is a bottom plan view of the body, showing the latch mechanism.

Referring now more particularly to the drawings, the numeral 1 designates a-car or wagon body formed of substantially truncate triangular end walls 2, a central longitudinal bottom deflector 3 of inverted-V form or having outwardly and downwardly sloping walls,

a bottom 4, and short side walls 5, below which are outlets or doorways closed by outwardly-swinging gates or doors 6, hinged at their upper ends, as indicated at 7, to the side walls 5.

The doors 6 are provided at'their lower ends with looking arms or members 8, having terminal hooks or lugs 9, adapted to be engaged to hold said doors in closed position by the hooked terminals 10 of transverse locking-bars 11, carried by a sliding lockin beam or bar 12, extending longitudinally below the bottom wall 4 and arranged to move in guides 13, secured thereto. One of the ends of the bar 12 extends beyond the adj acent end of the body, and the said extended end 14 is formed with a slot or opening 15 to receive the lower reduced end of an operating-lever 16, extending upwardly to a suitable height and provided with grips or handles 17 for its convenient manipulation.

It will be understood that a forward movement of the bar 12 will withdraw the hooks 10 from engagement with the locking members 9, so that the doors will be released to swing open by gravity, and that upon restoring the doors to closed position and sliding the bar 12 rearwardly the hooks 10 will again engage the members 9 to hold the doors closed.

The lever 16 is pivotally mounted upon a horizontal transverse shaft or axle 17, carried by angular brackets 18, mounted upon the adjacent end wall 2 of the body and having its ends extending beyond said brackets, as clearly shown in Figs. 3, 5, and 6. A'bailshaped lever or operating device 19 has the free ends of its arms pivoted to swing upon the extended ends of the shaft, and to this lever the forward ends of door-closing cords, chains, or cables 20 and 21 are attached and pass rearwardly and downwardly, respectively, over guide-pulleys 22 and 23, mounted on the shaft 17 between the brackets 18. The cords 20, two in number, also extend downwardly and outwardly over guide-pulleys 24, arranged below the brackets, and are connected to the front ends of the doors 6, while the intermediate cord 21 passes rearwardly through a slot 25 in the adjacent or front end wall 2 and through the space or chamber formed between the deflector 3 and bottom 4 and is provided at its rear end with branches 26, passing outwardly around guidepulleys 27, journaled in a slotted portion 28 of the rear end wall 2 and attached to the rear ends of the doors.

Assuming the doors to be locked in closed position, as shown, it will be understood that when the up er end of the lever 16 is drawn rearwardly t e locking-bar 12 will be moved forwardly, thus withdrawing the hooks 10 from engagement with the lugs 9, leaving the doors free to automatically swing open by the action of gravity and the pressure of the load thereon. In swinging open the doors draw upon the cords 20 and 21, which pull upon t e lever 19 and swing the same upwardly to a vertical osition, thus allowing the load to dump whi e the car or wagon is in motion, thus preventing the loss of time 00- casioned in transporting materials where it is necessary to bring the car or wagon to a complete stop in order to release the dumping-doors. When the invention is applied to a dumping-wagon, it will of course be understood that the operating mechanism will be mounted upon the forward end of the wagon and the levers arranged so as to be conveniently operated by the driver without leaving his seat.

To close and lock the doors, the lever 19 is forced downward to its normally horizontal position, which can be conveniently done by foot-pressure, whereby the cord may be drawn upon to swing the doors to closed po sition, and then by throwing the upper end of the lever forwardly the bar 12 will be moved rearwardly, so as to bring the hooks 10 into engagement with the lugs 9, whereupon the doors will be locked in closed position and the body of the vehicle adapted for the reception of the succeeding load.

The invention may be applied to railwaycars and carts and wagons used in the transportation of material, and its advantages in expediting the discharge of the material and in effecting a saving of time in the operation thereof will be apparent to those familiar with dumping conveyances of this type.

Having thus described the invention, what is claimed as new is 1. A dumping car or wagon provided with gravity-opening doors, door-closing mechanism set for operation by the opening move ment of said doors, a sliding locking-bar having rigid hooked arms to engage coacting locking members on the doors, and a pivoted lever for actuating said locking-bar.

2. A dumping car or wagon provided with gravity-opening doors having locking members, door-closing devices including an operating-lever set for operation by the opening movement of the doors, a sliding locking member having portions to engage the looking members on the doors, a lever for actuating said sliding locking member, and common supporting means for the two levers.

3. A dumping car or wagon provided with gravity-opening doors carrying locking members, a pivotally-mounted door-closing lever, connections between the doors and said lever, the latter being set for operation by the opening movement of the doors, a sliding lockingbar carrying engaging devices to interlock with the locking members on the doors, and a lever for operating said sliding locking-bar arranged coaXially mounted with the firstnamed lever, whereby both levers may be controlled by an operator from a common point.

4. A dumping car or wagon provided with gravity-o ening doors carrying locking members, a siding locking-bar having coacting locking members, a support, levers coaxially mounted upon said support, one of said levers being operatively connected with the locking-bar, and door-closing connections between the other lever and the doors.

5. A dumping car or wagon provided with gravity-opening doors carrying hooked locking members, a sliding bar mounted upon the bottom of the car and having latera ly-projecting rigid arms provided with coacting locking members, and means for sliding the bar.
